To all whom it maycmwern:

Be it known that 1, MICHAEL KIRSHNER, a

' subject of the Czar of Russia, residing in the Fig. 9.

city and county of Philadelphia, State of Pennsylvania, have invented anew and useful Improvement in Machines for \Vrapping Soap and otherArticles, which improvement is fully set forth in the followingspecifica tion and accompanying drawings.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the frame of the machine, onwhich is mounted the driving-shaft B, which carries the driving-pulleyC, the loose pulley D, and the sprocket-wheel E, around which latterpasses the sprocket chain F, which operates the printing roller G, saidshaft also carrying the cams H, J, K, L, M, and N. The cam H operatesthe lever P, which by means of a link Q imparts motion to thepawl-carrying elbowlever R, and consequently to the ratchet- Wheel S,secured to the shaft T, which latter has also secured thereon the bevelgear-wheels U and V, the former of these meshing with a gear-wheel NV,secured to a vertical shaft X, mounted on the frame A, and havingconnected with its upper end the brushes Y and Z. The gear-wheel Vmeshes with a gearwheel A, mounted on a vertical shaft B, having securedon its upper end the brushes G and D, (see Figs. 3and 19,) said brushesY, Z, G, and D applying adhesive material to a suitable portion of thewrappers, as will be hereinafter described.

The lever P hereinbefore referred to is loosely mounted on a shaft E onthe frame A.

The cam J operates an elbow lever F, loosely mounted on a shaft G on theframe A. The upper end of the vertical limb of said lever F carries aroller H, adapted to work against the stem J of a sliding plate K, (seeFigs. 11 and 12,) as will be hereinafter more fully described.

The cam K operates a lever L, secured to the shaft E and impart-s to thelatter arocking motion, which is transmitted to the levers M and N,secured to the shaft E, and said levers, by means of links P andQ,iinpart a reciprocating motion to a cross-head R, the object of whichwill be hereinafter fully described.

The cam L operates a lever S, secured to a shaft T on the frame A andimparts a rocking motion to said shaft, which in turn transmits thismotion to the levers U and V, secured to the shaft T. The lever U isconnected by means of a link WV with a risingand-falling frame Y,suitably guided in the frame A, and the lever V is connected by means ofa link X with said frame Y, so that the action of the cam L on the leverS and connected parts will cause the frame Y to move up and down.

The cam M operates a lever Z, secured to the shaft G and imparts arocking motion to said shaft, which in turn transmits the same to thelevers A and B secured to the shaft G. The levers A and B are connectedby means of links 0 and E respectively, with a cross-head D so that theaction of the cam M and connected parts will impart a reciprocatin gmotion to said cross-head. This latter has secured to its under side anadjustable knife or blade F which is adapted to cut the paper from whichthe wrappers are made, as

will be hereinafter fully described.

Secured to the frame A is a cross-piece G on the under side of which issecured a cutter-head H which works in conjunction with the blade F asmost clearly shown in Figs. 9 and 10. The cross-piece G is furtherprovided with guide-rods J on which slides the cross-head D and a plateK, which holds the paper to be cut, and from which wrappers are made, ina proper position relatively to the blade F and cutter-head H The cam Noperates a lever L loosely mounted on the shaft E. To the free end ofthis lever is connected a link M which imparts motion to the mechanismconnected with the inking-rollers for the printing-roller G.

Pivoted to the upper portion of the frame A is a frame N which isprovided with the inking-rollers P P P P and P and friction-roller Q theroller G being also mounted on said frame N the latter having its pivotor axis, as at B so as to either raise or lower the printing-roller G,this adjustment being necessary when articles of different sizes areplaced in the machine so as to be wrapped. It is evident that whenarticles of various sizes are to be wrapped all those of one size arecompleted before some of another size are placed in the machine, thisbeing done to prevent continually adjusting the print ing-roller G. Whenthe roller G has been adjusted, the clamping-screw S which is carried bythe frame N and travels in a segmental slot T in the frame A, istightened against said frame A, thereby retaining the frame N andconnected parts in adjusted position.

Pivoted to the frame N is an elbow-lever U the free end of one of itslimbs carrying the inking-roller P and the free end of its other limbhaving connected with it the pawl V that operates the ratchet-wheel Vwhich rotates the inking-roller P it being noticed that the elbow-leverU is connected with the link M hereinbefore described.

The printing-roller G is secured to a shaft Q loosely fitted in theframe N said shaft having also secured to it a sprocket-wheel R aroundwhich passes the sprocket-chain F, the object of which is to operatesaid roller G, as has been hereinbefore described.

The frame N has secured to it a hopper S adapted to receive the ink tobe supplied to the printing-roller G.

When cakes of soap are to be wrapped, two kinds of paper are generallyused, the one coming in contact with the soap being suitably waxed orcoated to prevent the same from adhering to the soap, and the other isordinary wrapping-paper from which are made the outside wrappers.

The upper portion of the frame A is formed with branches a and b, theformer of these sustaining a roll T of coated paper and the latter aroll U of ordinary paper.

To the upper portion of the rising-and-falling frame Y is secured apocket Y adapted to receive the article to be wrapped, and se cured tothe frame A is a pocket A for a similar purpose, said pocket A beingprovided with rollers A for closing the gummed ends of a wrapper. Thepocket Y is formed with a sleeve Z in which is guided the stem J of thesliding plate K.

The rising-and-falling frame Y is formed with slots V in which arefitted rollers \V of the levers X these latter imparting motion to thetoggle-levers Y', which operate the folders Z. (See Figs. 3, 4, 5, 6,and 7.)

Secured to the frame A adjacent to the pocket A are the hoppers Aadapted to receive adhesive material to be applied to the wrappers. (SeeFigs. 3 and 8.)

Secured to the frame A justabove each hopper A is a'stud B on which isloosely mounted a gear-wheel O to which is secured a head or disk D, thelower portion of which enters the hopper A and is consequently suppliedwith adhesive material.

Secured to each end of the shaft T is a gearwheel E, the same meshingwith the gearwheels C whereby motion imparted is transmitted to thegear-wheels O", and consequently to the heads or disks D so as to causethe latter to supply the brushes Y, Z, G, and D with adhesive material.

The operation is as follows, assuming that the articles to be Wrappedare cakes of soap: The free ends of the paper from the rolls T and U areinserted by hand between the printing-roller G and friction-roller Q andare then brought between the cutter-head H and plate K and when thedistance from the free ends of the paper to the knife-blade F is equalto the length required to form a wrapper the same is let go and the endspermitted to hang loosely, as shown in Fig. 1. Cakes 0 of soap are thenplaced in the hopper F the bottom cake resting on a portion of the frameA in the path of the cross-head R, the subsequent cakes resting one onthe other, as shown in Fig. 1, and the machine is now in readiness to bestarted. When this latter is accomplished, the sprocket-wheel E by meansof the chain F imparts motion to the sprocketwheel R and consequently tothe printingroller G thereon. iVhen the raised portion (1 of theprinting-roller G is working in connection with the feed-roller Qthepaper from the roll U will receive an impression from said raisedportion while passing between the same and the feed-roller Q and thepaper from both rolls T and U will be drawn there from until thedepressed portion a of the printing-roller G is presented to the rollerQ when the feeding of the paper from the rolls T and U ceases, owing tothe blank space f existing between the roller Q and the depressedportion 2 of the printing-roller, as shown in dotted lines at the rightof Fig. 1. hen the feeding of the paper from the rolls T and U ceases,the operation of wrapping is being accomplished, as will be hereinafterdescribed.

The printing-roller G is supplied with ink from the hopper S in thefollowing manner: The cam N imparts motion to the lever L which causesthe link M to operate the elbowlever U and consequently thepawl-andratchet mechanism connected therewith, and thereby rotate theinking-roller P which receives ink from the hopper S and transfers thesame to the roller P which latter, owing to the elbow-lever U is carriedfrom the roller P to the roller P and supplies the same with ink, andthis in turn, through the rollers P and P, supplies the printing-rollerG.

The wrapping of the articles is accomplished in the following manner:The cam K operates the lever L, which imparts a rocking motion to theshaft E, and consequently a similar motion to the levers M and N,secured to said shaft. The levers M and N impart a reciprocating motionto the links P and Q, and consequently a similar motion to the crossheadR, to which said links are connected. Vv'hcn the cross-head R moves inthe direction indicated by the arrow g Fig. 1, it will cause the cake ofsoap in its path to move with it, the other cakes in thehopper F 4resting on the top of said cross-head until the pieces of paper from therolls U and T which pass between said cross-head R and the sliding plateK are firmly held by reason of the cross-head R and sliding plate Kcoming together. The object in firmly holding the paper is to preventthe same from slipping while being cut. The cam M now operates the leverZ, secured to the shaft G, and impart to it a rocking motion, which istransmitted to the levers A and B secured thereon, and these, by meansof the links C and E impart a reciprocating motion to the cross-head Dand consequently to the blade F secured thereto. When the cross-head Dtravels in the direction indicated by the arrow h in Figs. 1 and 9, itwill cause the blade F to cut the pieces of paper a and i fed from therolls U and T In order to more clearly illustrate the wrappingoperation, a single sheet of paper is shown in Figs. 11 12, 13, 14:, 15,16, 17, 18, 19, and 20, it being evident that when more than one sheetis employed the additional sheets undergo the same operation describedfor a single one. As the cross-head R continues to advance it causes thecake of soap A in its path and the paper held between it and the slidingplate K, as well as the plate K itself, to enter the pocket Y as shownin Fig. 11, it being noticed that the plate K and its stem J traveltogether. Vihen the cake of soap is in the pocket Y three of its sidesare covered by the paper from which a wrapper is formed, as shown at j7:) 1, Fig. 11, and-the free end of the paper "a hangs loosely, as at n.The cake of soap, when in the pocket Y has its ends p 19 also covered bythe wrappingpaper, as shown in Figs. 13 and 15. These several folds areformed by the paper coming in contact with the walls of the pocket YWhen the wrapping operation has been thus far accomplished, the folds a,a a and a occur as a natural consequence, as shown in Figs. 13 and 14:.It will be noticed that portions of the pocket Y are cut away, as at a(see Figs. 12, 13, l i, and 15,) said cut-away portions being to permitthe folds a a a a to project beyond the ends of a cake of soap, andthereby prevent said folds from being crushed when the soap enters thepocket Y The cam K and connected parts now return the cross-head R toits starting-point. The cam L then operates the lever S, secured to theshaft T, and imparts a rocking motion to the same, which is transmittedto the levers U and V, and by means of the links W" and X causes therising-and-falling frame Y, and consequently the pocket Y thereon, tolower so as to bring said pocket Y on a line with the pocket A as shownin dotted lines in Fig. 11, it being noticed that when the frame Y islowered the stem J comes in the path of the roller II. The cam J nowoperates t-he elbow-lever F and causes the roller I'l thereon to travelin the direction of the arrow m Fig. 11. This causes the stem J, whichwas previously moved toward the roller 11 by reason of the cake of soapA entering the pocket Y and consequently the plate K, to return to theirnormal positions or startingpoints, as shown in Fig. 12. It will now benoticed that the plate K has removed the cake of soap A from the pocketY and caused the same to enter the pocket A The slots V hereinbeforedescribed, act as cams for the levers X so that when therising-andfalling frame Y, in which said slots are formed, is in itsraised position the rollers on said levers X will occupy a position atthe bottom of said slots V as more clearly shown in Fig. 6, and when vinthis position the levers X will have their upper ends ICO brought towardeach other or inwardly, as shown in Fig. 3, and thus cause the pivotedfolders Z", by means of the toggle-levers Y to close, as shown in dottedlines in Figs. t and 5 and in full lines in Figs. 16, 17, and 19. \Vhenthe rising-and-falling frame Y is in its lowered position, as shown inFigs. 4 and 5,

the rollers V hereinbefore described, will occupy a position at the topof the slots V as shown in Figs. 4 and 5, and thus cause the upper endsof the levers X to move away from each other or outwardly, as shown insaid figures, and owing to the toggle-levers Y connected therewith willopen the folders Z as shown in Figs. 4:, 5, and 16.

When a cake of soap occupies a position in the pocket A the free end itof the paper, as hereinbefore described, will, owing to the upper wallof said pocket A be caused to lie or fold over the fold j, and in doingso a portionm of the paper 10, hercinbefore described, will cover thatpart of a cake of soap opposite to the fold 71;, as clearly shown inFig. 12, and a cake of soap as thus far wrapped is illustrated in Fig.15. As hereinbefore described, the frame Y is now in its loweredposition, and consequently the folders Z are opened. (See Fig. 16.) Theframe Ynow rises, and in doing so closes said folders Z as shown in Fig.17, thereby folding the projecting portions a, a a and a against theends of the cake of soap, there then remaining triangular folds p, asshown in Figs. 17, 18, and 19. The cam H and connected parts, ashereinbefore described, now cause the brushes Y, Z, O, and D to revolvewith their respective shafts X and B, and thereby apply the adhesivematerial g to the triangular folds p, as shown in Figs. 8 and 1.9. Thepocket Y after receiving another cake of soap from the hopper F againlowers, and said cake, after undergoing the operation of wrappinghereinbefore described, reaches and bears against the cake A and owingto the sliding plate K causes the cake of soap N, as thus far wrapped,to pass between the rollers A which press the folds 13 against thosealready formed on the ends of the cake of soap A and owing to theadhesive material thereon cause said folds p to remain in foldedcondition and completes the wrapping operation. As hereinbeforedescribed, the frame Y when lowered opens the pivoted folders Z so thatthe latter in no way interfere with the folds of a cake of soap when thesame is passing from the pocket Y to the pocketA and the cake of soap,after passing between the rollers A reaches the chute I3 and is directedby the same from the machine to a suitable receptacle, box, (K70.

IVhen it is desired to wrap cakes of soap of small size, the free end ofthe frame N is lowered, so as to cause the printing-roller G to occupy aproper position relatively to the required size of the paper to be cutfrom the roll U and from which a wrapper is formed, SO that theimpression from said roller will be in a proper part of the paper. It isevident that when the free end of the frame X is lowered thesprocketchain F will hang loosely on the sprocket-wheels E and R Inorder then to take up the slack in said chain, a screw N in the frame Ais loosened, thereby permitting the swinging frame N, which has asegmental slot through which said screw N passes, to be swung on itspivot N so as to cause a roller N on said frame to bear against thechain F, and thus tighten the same. This being done, the screw N isproperly rotated, so as to firmly hold the roller 3 in its adjustedposition against the chain. The pockets A Y may be removed from theframe A, and pockets differing in size, but similar in construction,employed in their places, this change becoming necessary when articlesof different sizes are to be wrapped.

\Vhen different -sized articles are to be wrapped, the feed is adjustedby placing in the machine a printing-roller G, whose raised portion atwill, when working in connection with the friction-roller Q feed thepaper from the rolls T and U a length corresponding to the size of thearticle to be wrapped. For instance, when a small article is to be wraped the printing-roller G will have but a short peripheral raisedportion 1. When a largersized article is to be wrapped, the roller Gemployed in wrapping the small article is removed from the machine, andone with a longer peripheral raised portion d is put in its place. Inthe drawings the raised portion cl is shown the length of asemicircumferenee and rollers each having a different length of raisedportion cl may be used. All rollers G are of the same diameter.
